BAND-SECURlNG MECH ANlSM FOR GRAIN-BINDERS.

$1ECIPICATION forming part of Letters Patent No. 319,963, dated June 16,1885.

(No model.)

To all whom it may concern,

Be it known that I, JOHN S. DAVIS, of'loledo, in the county of Lucas andState of Ohio, have invented certain new and useful Improvements inBand-Securing Mechanism of Grain Binders, of which thefollowing isaspecification.

My invention chiefly relates to improve ments in that cl ass ofgrain-bindin g mechanism for clamping, knotting, and cutting the binding material in which provision is' made for supplying the bindingmaterial to a knotter, during the formation of the loop of the knot,from the band ends, instead of from or mainly from the banding portionorlength of the binding material which encircles a bundle and isincluded in the loop formed by crossing or bringing together at or nearthe knotter that portion of the binding material next the end which isclamped and that portion next the end passing to the binder-arm.

Types of the class of mechanism to which my present invention relatesare shown and described in United States Letters Patent forotherinventions of mine, granted June 5, 1883, No. 279,082, July 31,1885, No. 282,445, and July 8, 1884, No. 301,808.

Instead of employing, in connection with co-operating devices, avibrating knotter, as shown in the referred-to patents of June 5, 1883,and July 31,1883, or an oscillating cordholder, by the turning andreciprocating member of which cord is taken up at the ends of the bandsand supplied to the knotter, as shown in the abovementioned Patent No.

- 301,808, I now employ a non-turning cordholder, the movable member ofwhich has imparted to it a movementof reciprocation only, and isprovided with a loop-retainer by means of which cord is taken up at theends of the bands to be given out during the formation of the knots.

In accordance with my present improve ments, I employ various featuresdescribed or referred toin the before-mentioned patents, whilesimplifying the construction and lessening the cost of the mechanism nowused as compared with that heretofore employed.

The accompanying drawings, which sufficiently represent a suitableapplication of my improvements, show only those features illustration ofwhich, aided by reference to the before-mentioned patents vif necessary,is thought to be needed to convey a proper understanding of theimprovements herein k claimed. Some of these improvements may, however,be used without the others, or be employed in connection with mechanismdifferingin some respects from that shown and hereinafter particularlyreferred to. i

Figure 1 is a plan view of the entire band secaring mechanism, the coverof the knotter box or casing for this mechanism being removed and theparts represented as in their normal or. stationary positions. Fig. 2 isa plan view showing a portion of the knotterbox without its cover, and aportion of the binder-arm with some'parts of the mechanism omitted, andthe movable member of the cord-holder in section on the line 2 2 of Fig.9, the parts being represented as in the positions they are caused toassume at about the time the movable member of the cord-holder is to beprojected and when the strain exerted by the knotter on the band end hasdisengaged it from the loop-retainer of the movable member of thecord-holder.

Fig. 3 is a plan view of a portion of the cover of the knotter-boX. Fig.4 is a View partly. in side elevation and partly in section on the lines4 4 of Figs. 1 and 3, representing a device by the actuation of whichthe cord is adjusted in proper position to be engaged by the knotter.Fig. 5 is a view partly in side elevation andpartly in section on theline 5 5 of Fig. 1, the knotter being omitted. Fig. 6 is an endelevation, the binder-arm beingpartly shown, and the parts representedas in the po sitions they are caused to assume when aknot is nearlycompleted and the binder-arm about to commence its upward movement. Fig.7 is a view partly in elevation and partly insection on the line 7 7 ofFig. 2, showing a lever connected with and serving to actuate thecord-adjuster. Fig. 8 is a bottom view of the movable member of thecord-holder, a portion of a band end being represented in dotted linesas passing about the loop-retainer, and in full lines as having beendrawn from the loop-1e tainer preparatory to being released by theclamp. Fig. 9 is a side elevation of the movable member of thecord-holder, a portion of 5 the band end being represented by dottedlines 9. Figs. 11 and 12 are views in elevation of opposite sides of themovable member of the cord-clamp, its shank being broken away and theband end omitted.

A knotter, A, preferably in all respects such r as that set forth in thebefore-mentioned Patent No. 301,808, and the same, except that it doesnot vibrate and does not have a jointed shaft, as that shown anddescribed in the above specified Patents Nos. 279,082 and 282,445, hasits shaft B mounted to rotate in suitable bearings,a b, the shaft beingprovided with the actuating-pinion at its inner end, and turning inopposite directions backward and forward, so as to cause the knotter tofirst en- 2 5 gage the cord presented to it by the binderarmC as itturns backward, and then form the loop and knot as it turns in the otherdirection,or forward, as heretofore.

The knotter-shaft B is provided, as before,

0 (see my aforesaid Patent N 0. 301,808,) with a roller-carryingtappet-arm, D, the tappet-roller d, acting upon a lug which projectsupwardly from the end of one arm of an elbow-lever, E, the opposite armof which connects, by means 5 of a slot at its end, with adownwardly-pro- 40 to thebottom of the knotter-box G, and the end ofthis lever which is acted upon by the tappet-arm vibrates close to thebottom of the knotter-box. By these means it will be seen that thereciprocating holder-shaft is actuated,

as before, to project the movable member of the cord-holder, to befurther on described.

Inorder that the cord-holder shaft at its inner end may be locatedsuflicient-ly far from the pivot e of the elbow-lever E to admit of 5cthe action of the lever upon the shaft throughout a proper extent of thesweep or throw of the lever without cramping or binding the parts, andyet not interfere with the location of the knotter and cord-holder closeto each other, the holder-shaft is inclined instead of being parallel tothe knotter-shaft,'the dis-- tance between the two shafts being greatestat their inner ends.

The holder-shaft F is supported so as to be no capable of reciprocatingin the direction of its length in suit-able bearings, H and h, thebearing it being at the inner end of the knotterbox, and the outerbearing, H, formed with a bracket secured to the bottom of the knotter--3 5 box.

A'spring, g, coiled about the holder-shaft, bears atits outer endagainst the bearing H and at its inner end against a nut, I, adj ustablysecured to the shaft by means of the threaded portion i thereof. Thespring acts upon the holder-shaft in opposition to the action of theelbow-lever E, and serves to slide the shaft inward after its outwardmovement by the le ver, as will readily be understood.

The movable member J of the cord'holder is connected by means of itsshank j with the outer end of the shaft F, close to the bearing H. Topermit of ready adjustment of parts and facilitate repairs, the shank jis detachably connected with the holder-shaft by means of a screw orbolt, k, as shown. The shank of the cord-holder reciprocates'in aguideway or open bearing, K, at the outer end of the knotter-box. As inthis instance shown, the cord-holder shank is rectangular incross-section, and fits sufliciently snugly in its guideway-bearing toprevent any turning movement of the reciprocating member of thecordholder and its shaft. Obviously turning movement of the holder-shaftand member J of the holder might be prevented in other andequivalent'way, as by spline-and-groove connection between the shaft andone or both of its bearings.

The reciprocating non-turning member of the cord-holder, in addition tobeing so constructed as to clamp and cut the cord in connection withafixed member of the holder and a fixed knife, which are soon to bedescribed,

is made to engage and temporarily retain a portion of the cord next theclamped end of each band, the cord so retained being given up undertension to the knotter during the formation of a knot and preparatory tothe release of the clamped end of a band and the completion of the knot.The details of construction of the two members of the holder are as inthis instance shown, as next to be described.

The fixed member L of the cord-holder is formed of some suitable,durable, and yielding or compressible material, preferably leather,secured in a cavity or niche in the outer end of the knotter-box, andprovided with a recess, Z, in its face. The leather is detachablyclamped in place by means of a plate, M, the edge of which forms thefixed knife, and abolt and nut, m, as will readily be underderstood frominspection of the drawings. The fixed knife-plate bears against theinner side of the holder-1eather Lthat side next the knotter; andbetween the opposite or outer side of the leather and the face recess lthereof it forms a bearing, a, against which a loop-retainer, N, of thereciprocating member of the cord-holder presses, as further on to bemade apparent.

The shankj of the cord-holder reciprocates above the fixed member of theholder, and the inner end of a downwardly-projecting rib or lip, 0, ofthe reciprocating member of the holder enters the recess l to clamp thecord.

A movable knife-section is formed by the inner edge of a downwardprojection or IIO shoulder, p, of a plate, P, riveted or otherwisesecured to the inner side of the holdershank.

Beneath the level of the holder-shank, and between the clamping-lip 0and knife-plate shoulder 19, there is a recess or opening, 0, in thereciprocating member of the holder. This opening extends to the bottomand end of the member J, and allows of the ready escape of defachedparticles of cord, such as may fret off from the band ends, and thusprevent clogging of parts.

The loop-retainer N is formed by a later ally and vertically extendinglug at the outer side of the reciprocating member of the cord holderthatside most remote from the knife. As shown, the loop-retainer extendsfrom the top of the cordholder member J downwardly, terminating at itslower end beneath the level of theholder-shank and above the level ofthe lower surface of the lip 0. At its lower end the loop-retainer iscurved inwardly,or to ward the fixed member of the cord-holder, as at q,and its lower edge is rounded ofi or inclined toward the lip 0, as at r.The curved end q of the loop-retainer extends inwardly, so as to pressagainst the bearing 11, provided by the fixed member of the holder, whenthe cord is clamped in the recess Z by the lip 0, but with only a slightdegree of pressure, or at least a pressure less than that of the lip 0against the cord in the recess Z, the lip 0 extending farther inwardthan the end of the loop-retainer, and consequently bearing withsufficient force against the tix-ed member to properly clamp the cord.

The knifeplate shoulder 12 and the lip 0 are provided with notches s tin their under surfaces to be engaged by the cord and prevent accidentaldisplacement'of the band ends.

From the above description, with the aid, if needed, ofthebefore-mentioned patents and application, the operation of the devicesso far explained will be understood to be as follows, assuming thatproper binding mechanism and mechanism for starting the bindingmechanism in action upon the accumulation of a gavel are provided Theend ofthe cord having been clamped after being first passed about theloopretainer, (seeFigs- 1 and 5,) cord will bepassed from the holder tothe knotter when by the rotation of the knotter it reaches a point inits operation when cord is to be taken from the holder to form the loopof knot, the pull by the knottcr on the clamped band end drawing thecord down and around the edge of the loop-retainer and along between thecurved lower end and the hearing it, against which it is pressed andyieldingly held. The loop of cord extending from the lip 0 and recess Zto and around the retainer N, being held with sufficiently slightpressure, is, when properly strained, allowed to slip down over the endof the retainer and pass along in between the bearing n and the adjacentsurface of the retainer N, and to pass to the knotter by the give orcompression of the bearing against which the retainer works, as well asby a slight outward movement of the reciprocating cordholder memberagainst the force of its spring in event of such movement beingnecessary. The cord having been pulled over the end of theloop-retainer, and along between the edge of the retainer and thebearing n, and the band end having passed from the position in which itis shown in Figs. 1 and 5, and by dotted lines in Figs. 8 and 9, to thatin which it is represented in Fig. 2, and by full lines in Figs. 8 and9, the projection of the reciprocating member of the holder by theaction of the knotter-shaft tappet and the elbow-lever on thecord-holder shaft next releases the band end, and the knot is completedand cast off in manner needing no description here. The reciprocatingholder-section as moved outward crosses above and hooks over the cordnext the binder-arm, and the inward move ment of this holder-section byits spring, when allowed to act by the release of the elbow-leverbythetappet,cutsandclampsthecord. Next, the binder-arm is moved back toits inoperative position, drawing the cord about the loopretainer andengaging it with the notches s t,

preparatory to a repetition of the above-described steps.

In order to insure engagement of the cord 7 by the knotter, by guardingagainst the possibility of the cord being accidentally pressed downwardby the grain or otherwise out of the reach of the knotter, l providemeans, such, as soon to be described, by which the cord is pressedupward and supported in proper po- IIO ficiently wide at the properpoint to allowof the ready exit of the knots formed in the bands. Anendwise reciprocating cord-adjuster, T,

acts upon the cord after it has been presented.

beneath the knotter by the descent of the binder-arm, and presses thecord upward along the upwardly-extending guideway Q, thus causing thecord to bear against the knotterand to slightly incline outwardtherefrom so as to greatly facilitate engagement of the knotterjaws withthe cord, the k notter, as hereto fore, being first turned downward tocause its jaws to pass beneath the cord, and then turned in the oppositedirection to hook and engage the cord and form the knot.

The details of construction of the cord-adjuster, its connectingmechanism, and the manner of actuating it, as in this instance shown,are as follows: The cord -adjuster is located close to the inner wall orside of the knotter box, is supported and guided at its outer end in aslot, U, in the end wall of the knotterbox, has a nose, V, inclined orsloping upward from its extreme outer end or rounded point to aknotter-box near its inner side.

shoulder, 12, and is formed with an incline, w, on its lower edge nearits outer end. This incline 10 works in contact with the rounded bottomwall, a, of the gnideway-slot U, and serves to elevate the nose of thecord-adjuster when it is projected. The cord-adjuster is recessed or cutaway at top from the shoulder 12 to a shoulder, W, at its inner end. Aguidestud, -v, projecting inwardly from the side of the knotterbox,crosses above and close to the cord-adjuster, between its shouldersv andW. The cord adjuster is perforated at its inner end, and has jointedconnection with a horizontally-vibrating lever, W, the rounded outerend, to, of which passes through the perforation in the cord-adjustersuflieiently loosely to allow of proper play of the parts, and projectsinto a recess in the side of the knotterbox. The lever W is pivotallyattached near its heel end to the bottom of the knotter-box by apivot-bolt passing through the perforated boss or hub 00 of the lever.At the heel end of the lever WV there is provided a perforated slottedlug, w, by means of which and a suita ble pivot the lever has jointedconnection with the inner end of an endwise reciprocating iounded bar orpush-rod, X,which is supported at its outer end in a bearing formed by aperforation, X, in the end wall of the knotterbox. A spring, Y, iscoiled between its ends about a stud, Y, suitably secured to the bottomof the knotter-box, and projects at its ends in opposite directions, oneend bearing against the heel of the lever W, and the other pressingagainst a stop or butTcr, 1 preferably of rubber, secured by a bolt tothe bottom of the A notched side lug, y, serves to insure proper contactof the spring with the lever, the spring engaging the notch of the lug.The outer end of the push-rod is provided with an incline, z. At thepoint or nose of the binder-arm it is provided with the rounded innersurface or iiicline, Z. Asupport and guideway, Z, for the binder-arm, atand near its nose, is shown as formed by a bracketarm secured by screwsto the under surface of the bottom of the knott r-box and bent upward atits outer end, the space between the inner surface of the upwardly-extending end 2 of the guideway-suppoit andt-he end of theknotter-box being such as to admit the binder-arm freely, while preventing any lateral or outward movement thereof.

From the above description it will be seen that the cord-adjuster isoperated in the following way: Upon the descent of the binderarm itsnose enters the guideway-support,bearing at its outer side against therounded inner surface of the end 2 of the support, while the incline Zacts against the inclined end of the push-rod, thrusting this rodinward, moving the lever with which it is connected, and proj ecting thecord-adj uster into the position in which it is represented in Fig. 2,and by dotted lines in Figs. 4 and 5, and in this way directing the cordfrom the position it is first caused to assume by the binder-arm (seeFig. 4) to that in which it is represented by dotted lines in Figs. 1and 4, so as to be readily engaged by the knotter. When the binder-armmoves upward and leaves the push-rod free,it is thrust outward by thespring Y to the limit of its movement in this direction,and thecordadjuster is retracted. The suddenly-imparted inward movement ofthe'push-rod and cordadjuster is gradually arrested by contact of theirlever with the yielding stop y, and the parts then assume their normalpositions under the controlling influence of their actuat ing-spring,the push-rod projecting into the path of the binderarm, so that theabove-described steps are repeated upon the next actuation of thebinder-arm.
